separated standards 16 and 17 for supporting the glue-applying rolls A,B, C, and D1 These glue-applying rolls are preferably arranged so thatone or more applications of the substance or glue from t-he tank Will bemade by them to a blank passing through the machine. Furthermore, theyare all preferably supported so that they tend to gravitate towardthedistributer roll and so that they are freely movable toward the roll oraway from it. We also prefer to provide means for nicely regulating oradjusting the position of the glue-applying rolls with respect to thedistributer roll so as to regulate the distance of the glue-applyingfaces of the rolls from that of the distrihuter roll. In this way thefaces of the rolls may be made to nearly contact without pressing eachother and a very nice regulation is obtained for the coating of gluewhich is conveyed from the distributer roll to the glueapplying rolls.In order to accomplish this, We prefer to arrange the glue-applyingrolls in pairs such as the pair A and B. These rolls are preferablyformed with separated glue-applying faces 19"IL and 19", the formerbeing on the roll A and the latter on the roll B. These glue-applyingfaces are arranged out of alinement with each other and the rolls arearranged relatively close together with the collars of one rollintermediate the collars of the other roll so that the glue-applyingfaces of one roll extend beyond the glue-applying faces of the otherroll of that pair, that is, if the rolls are viewed in end elevation,their peripheries apparently intersect.

Beyond the rolls A and B are provided means for completing the coatingoperation which is commenced at these rolls. This means operates to coatany spaces left uncoated by the rolls and may apply a second coat overpart of the area of the blank. For this purpose, in the presentembodiment, in addition to the rolls A and B, We have illustrated twoother rolls C and D which form a cooperating pair. These rolls aresimilarly constructed and similarly arranged to the rolls A and B. Theremay be as many of these. different pairs,l of rolls as desired. Eachpair of rolls coats any uncovered gap left by the other rolls, andpreferably suh-v stantially coats the entire surface of the blank.

The rolls C and D are arranged with their glue-applyingv peripheralfaces 19c and 191 out of alinement with the glue-applying peripheralfaces of the rolls A and B. This arrangement is preferable because it.insures the complete application of the glue to the blank. Thedesirability of this arrangement appears very clearly froma reference toFig. 4, in 1which the glue-applying faces are represented as being theperipheral faces of collars 20, formed integrally on the rolls.

By arranging the rolls C'and D so that they do not aline with the otherrolls, the glueapplying faces 19c ofthe roll C are in a position toapply a coating of glue along the lines of the adjacent edges of vtheglue-appyling faces 19i and 19h. In this Way, the second pair of rollsis made to apply a. second coat and applies that coat in'proper positionto till up any gaps which may possibly be left by the first pair ofrolls. In order to support the rolls the standards 16 and 17 arepreferably provided with open sockets 21 and these sockets receive andguide the ends of the shafts 22 of the glueapplying rolls. Theglue-applying rolls are 30 all preferably positively driven and this maybe accomplished by means of a long faced gear wheel 23 on the shaft 14(see Fig.

2) and meshing with pinions 24 rigid with the shafts or gudgeons 22, andthe ends of 35 the shafts of these rolls simply rest freelyi in thesockets (see Fig. 3). It is evident from an inspection of Fig. 3 thatthe pinions 2& would interfere with each other unless they were arrangedout of alinement with each other, as indicated in Fig. 2. We prefer toprovide means for simultaneously adjusting all of these rolls A, B, Cand D. For this purpose We prefer to provide a cam 25 which isadjustably supported on 95 the axis of the shaft 1t, and this cam has aplurality of cam edges 26 which en- -gage respectively with the shaftsor gud- 'geons 22 of the different rolls. This cam is duplicated at theother end of the machine and evidently by rot-ating these cams in onedirection, the rolls could all be adjusted inwardly, yWhereas if the camrotated in the opposite direction, the rolls would all be adjustedoutwardly. Each of these cams 25 105 has a Wing with a slot 25a whichreceives a clamping stud 25 secured in the frame. By means of thesebolts the cams can be clamped in'any adjusted position desired. All theglue-applying rolls, however, constantly tend to gravitate toward thedistrihuterV roll'and so that their glue-applyingl faces tend to comeinto contact-With the peripheral face of the distributer roll.

Between the rolls A and B, We prefer to provide means for coperatingWith the rolls 'to assist in guiding the blank through the machine. Thisguiding means is preferably in the form of a small presser roller V27.This roller preferably has a plurality of 12.0 equidistantcircumferential ribs 28, and at each end of the roller enlargements orheads 29 are formed which roll on and are Y supported on correspondingenlargements or heads 30 on the rolls A and B (see Fig. 2). 125 Thisarrangement operates to hold the presser roller at a'suitable distancefrom the glue-applying faces of the rolls A and B, that is, so that theperipheries of the ribs 28 lie very near but do not touch theglue-aparrangement for guiding plying faces. We prefer to adopt asimilar the blank as it passes from'the roll C to the roll D, and thisguiding means preferably comprlses a presser roller 31; the details ofthe construction and arrangement of this roller 31 are the samea-s'those just described in connection with the other presser roller.

Between the rollers B and C,we prefer to provide a presser roller Ewhich is of relatively large diameter and of considerable weight, andthe ends of this roller are provided with circularheads or wheels 32which roll upon the coperating heads 30 on the ends of the rolls B andC, and this operates to impart the weight of the roll E to the rolls Band C, at the same time holding the Vcircumferential ribs 33 of thisroller out of contact with but adjacent to the'peripheral faces of therolls B and C. In order -toY may, if desired, be attached in common to abar 35. 'These fingers are preferably of substantial ,U-form, the bendof the VU being disposed toward the roll B from which the blank isreceived, and the free legs of the U projecting toward the roll C, andin such a way that they will operate to strip the blank ofi' of theglue-applying surface of the roll B and direct it against the surface ofthe roll C. For this purpose, the forward ends of the guide lingers 34preferably Aproject inwardly beyond theperiphery of the roll B. Similarguide fingers 36 are provided for talng the blank oil' of the surface ofthe last roll D and these fingers 36 direct the coated blank onto theupper run of an endless conveyer 37 which conveyor is supported on aconveyer frame 38 which extends out over the tank 11. This con- Veyerpreferably consists of aplurality of belts 37 guided around suitablepulleys 39 and 40 supported on this frame. The frame 38`is preferablysupported on the frame 10 on a suitable pivot 41, enabling it to beswung up when desiredf The pulleys 39 are carried on a common shaft 42driven continuously when the machine is in operation .by means of algear 43 at its end, actuated by gears 44 and 45, the latter of whichmeshes with the aforesaid gear 23. We provide means to prevent thecoated blanks from curling up at their edges. Above the belts 37 aplurality of narrower belts 46 are provided which are to .keep thegluecoated blank'fromcurling up.. These belts run substantiallyvparallel with and near the belts 37, their lower ends passing aroundpulleys 47 on a common shaft 48, and this shaft 48 is drivencontinuously by a gear 49 on shaft 42 which meshes with the gear 50 onthe shaft 48. While the coated blanks are lying on the conveyor 37 theyhave their glued slde down. As each blank passes V,lower 15 to theglue-applying rolls.

around the pulleys 40, it is stripped olf the belts 37" by suitableguides 51 (see Fig. -1) and each blank then falls down onto an 1nclinedshelf or delivery table 52.

When the gluing machine is in operation, it is usually run inconjunction with another machine such as a wrapping machine which isbeing fed with the glued'wrappers. The operator of such machineconstantly removes each glued blank as it arrives at the table 52. Thewrapping machine and the gluing machine are both controlled by theoperator of the wrapping machine so that when the wrapping machlnestops, the gluing machine also stops and this arrangement prevents anypossibility of two or more wrappers arriving on the delivery shelf 52 atthe same time and so that they could become stuck together. Ifnecessary, the belts 46 may have a special form particularly adaptingthem to their purpose. For instance, we may employ coiled wire belts,the coils of which tend to prevent the curling edges fropi slipping bywhen they are trying to cur The wallower roller 15 is preferably hung ontsgudgeons 57 between two arms 54 and these arms are mounted to swing onrotating pivot pins 55 at the sides of the tank,

.and are adjustable on said pivots by means of adjusting screws 56. Thegudgeons 57 of the roller 15 are about on a line between the pivots 55and the shaft 14 so that by swinging the arms 54 upwardly the roller 15can be swung out of the tank and also out of engagement with thedistributer roll 13 which conveys the glue from the WE1- y swinging theframe 38 upwardly, the rolls C and D as well as' their adjacent roll 31will be exposed so that they can be readily removed from their bearings,if desired.

The sheets or blanks 58 which are to be coated with glue are preferablysupported in a pack 59 with the sheets 58 on edge ('see Fig. 1). Theymechanism for supporting this pack and for oscillating the pack so asto present the foremost sheet to the glueapplying roll A is covered inPatent No. 1,152,358 dated August 31, 1915. This feeding mechanism willnow be briefly described :y

It comprises an inclined table 60 which is provided with a rack 61 whichis reciprocated by means of a cam 62 on acam shaft 63. The cam operatesa rock-lever 64, the short end. of which isconnected at 65 with the rack61. A spring 66 tends to pull the rack outwardly on the table and in adirection to'hold the roller v67 of the lever 64 against the cam62. Theconnection at 65 is a pin and slot connection. Back of the pack 59 thereis mounted a follower or pusher 68 preferably comprising a base or slide69 mounted to travel inwardly along the table. 0n the base 69, ispivoted a gear las j There ore, this upward movement of the j rack willpull the gear wheel 70 and the base wheel and a-pawl carrier 71, saidpawl carrier having a pawl 72 which-engages the teeth of the gear wheel70. As the rack 61 moves in an outward direction on the table,

it moves the gear wheel -70 in a right hand..

which is pivotally mounted at 74 on the basev 69, the said awl carrierbein connected by a link 75 wlth this plate. o eration of the machinethis late 73 simp y oscillates on its pivot 74. I the forwardoscillation of the plate should be excessive such as that indicated inFig. 1, the yend of the pawl 72 comes out of en agement with a latch 76and then frees itsel automatically from the teeth due to the specialconstruction of the nose 77 of this awl. When this occurs the plate 73falls ack toward the left, as viewed in Fig. 1 and the pawl 72 gets anew engagement with the teeth of the gear. As the pawl 72 moves backwith the plate 73, it engages the shoulder 78 of the latch 76 andpushesthis latch back against the resistance of its spring7 9, and the latchis then moved back into its normal position by its spring, pushing theawl 72 mto engagement with the teetho `the gear wheel.

In this way the pawl automatically takes a newv grip on the gear 4wheelif the plate 73 has an excessive forward oscillation. In ad' dition tothis there is provided a'detent pawl 80 which is mounted on the base andpressed into engagementwith the teeth ofthe gear wheel by a spring81.1,"'If suchen excessive movement of the oscillating plate 73 occurs,such as just described, a tooth of the gear wheel 70 will move ast thepawl 80 and the pawl will prevent t e gear wheel from re-A turnin whenthe rack'6 moves upwardly.

69 upwardly on the inclined table. In order to prevent the pusher fromslipping back on. the inclined table and for holding th ground gained`in the upward movement given toV 1tV by the rack, we provide a ratchetrack 82 with inclined teeth and we also ro vide a pawl Y83 which mesheswith t ese teeth and prevents the base from slipping back. Thispawl ispressed into en agement with the ratchet rack by a suitab e spring 84.The rack 61 is suitably guided by pin and slot connections 85 on theunder side of the table.V

In order to adjust the height of the pack with relation to the roll A,we prefer to provide a manually operated adjusting screw 86 which passesthrough a threaded sleeve or nut 87 attached to the table 60. Inorder'to maintain ,theiengagement with the cam 62 on the shaft 63, thecam 62 is arranged to slide along dn the shaft 63 n the normal throughthe medium ,of a feather running in a slot 87 in the cam shaft. Anadjustable stop 88 is provided for limiting the forward movement of thepawlcarrier 71.

In order to e'ect a uniform ydistribution of the glue on the distributerroll 13, we prefer to constantly shift that roll longitudinally to andfro on the Wallower 15. In order to accomplish this movement in a simplemanner, we prefervto provide a gear cam 89,`the `rim of whichv is warpedout of its proper plane and thus constitutes a cam (see Fig. 2) so thatthe edges of the rim operate upon a grooved roller 90 fixed to shaft 14,and shift the shaft longitudinally in its bearings. At the same time thegear teeth on the rim 89 mesh with corresponding gear teeth 91 at thebottom of the grooved roller 90 so that this cam gear not only a'ordsmeans for shifting the shaft 14, but also affords means for rotating Byreason of the long face or gear 23 driving engagement is maintained withthe pinions 24. 1

In order to support and guide a pack 59 of the sheets on one edge, weprefer to provide a guide rod 92 which is suitably supported in anadjustable bracket 93 on the` table, and this guide rod paes through asuitable slot 94 in the oscillating plate 73.

The c am shaft 63 is preferably continuously driven by a shaft 95 whichaetuates it through suitable bevel gears 96.

When the gluing machine is in operation,

the operator starts the gluing machine and also starts the feed movementfrom the peck-` from thepack.u The foremost Vsheet adheres to the Troll`A and rolls up on it so that the upper edge of the foremost blankorsheet passes under the guide roll 27 and is then guided onV throughthe machine sol that the blank /will pass on through the machine andbetween the belts 37 and 46.
